Dallas Police and the Federal Bureau of Investigation arrested a 60-year-old Dallas man and now charged with the 1984 capital murder of Mary Jane Thompson. This had been a murder case that has become very cold for the past few decades.

DFW CBS reported that Dallas County Criminal District Attorney John Creuzot announced that the District Attorney's Office, along with the DPD and FBI arrested 60-year-old Edward Morgan. It was 38 years ago that Thompson had been found murdered behind a Dallas warehouse on Irving Boulevard.

Police discovered that she had been sexually assaulted and murdered on February 13, 1984. Police had been searching for the killer since. Dallas Police reopened the case in 2009 as DNA technology made advancements, allowing them to do so.

NBC DFW reports that In 2018, DPD Cold Case Homicide Detective Noe Camacho reopened the case and worked on some new types of forensic testing techniques. Two years later the FBI joined the investigation. The case was sent for forensic genetic genealogy analysis. This is the same technology and testing that was used to capture the Golden State Killer. Through this analysis, Morgan was identified as the suspect. Just recently DNA testing proved his sample matched the sample from the swab taken in the 1984 autopsy.

ABC 8 reports that Edward Morgan now faces a single count of capital murder and is currently held at a Dallas County Jail. The DA's office looks to continue working with law enforcement to continue to use these advancements in forensics to identify, arrest and prosecute those who continue to evade police.
